Show 268 MR. C. O. WATERHOUSE O N [Feb. 15, are slightly prominent; the disk is very strongly punctured, but the punctures are not very numerous, although from their large size there is not much space between them; the sides are rusty yellow. The elytra are rusty yellow, with an oblong black spot common to both elytra at the scutellum, and the apical third is also black ; each elytron has three strong costae, the lateral one is rather less strong than the others, and at the apex turns aways from the apical spine : the first and second interstices have two lines of strong punctures, a fine ridge dividing the lines at the apex ; in the third interstice there are three lines of punctures at the apex ; the sides are finely serrated ; the external angle at the apex is produced into an acute spine, which is slightly concave at its base above. The middle of the sterna, and the intercostal process of the abdomen are pitchy-red ; the legs are tinted with aeneous ; the femora have the base pitchy-red, the four posterior femora have a small acute spine near the apex below. 31. ODONTOTA ANNULIPES, n. sp. (Plate XXX. fig. 18.) O. nigra, opaca ; fronte, thoracis lateribus, elytrisque ferrugineo-ochraceis, his sutura nigra, femoribus basi ferrugineo-annulatis. Long A\ lin. Antennae moderately long and stout. Thorax a little impressed at the base, with a very fine raised line in the middle in front. Each elytron has four costae; the two dorsal ones are very strong ; the third is sharp over the shoulder, interrupted in the middle, and very fine at the apex ; the fourth is entire but fine ; the lines of punctures are strong and distinct; the suture and a small mark under the shoulder are black. The middle of the sterna and inter-coxal process of the abdomen are pitchy yellow. 32. ODONTOTA ? sp. inc.1 0. nigra, opaca; elytris sanguineis, basi apiceque nigris, ad apicem obtuse rotundatis, breviter acute serratis. Long. 3| lin. A single example without antennae, which I therefore indicate as a species without giving a name. * 33. ODONTOTA APICIPENNIS, Chapuis, An. Soc. Ent. Belg. 1877, xx. p. 18. Hab. Ecuador. This species is known to me only from description. 34. METAXYCERA QUADRIGUTTATA, II. sp. (Plate XXX. fig. 21.) M . sanguinea; elytris olivaceo-a?neis, singulis maculis duabus sanguineis. Long. 4| lin. Thorax velvety, shining on the disk in front, where there is a well-marked longitudinal impression. Scutellum pitchy. Elytra depressed on the back, finely crenulate at the sides, and more distinctly so at the apex; the disk of each elytron is dull and slightly velvety-black; the lines of punctures are very deep and distinct; 1 The genus is doubtful, there being no antenna?.-0.
